问题
After importing the maven project in Intellij. It started a background task of indexing and building. Build task is not getting complete. I checked the Intellij logs and found a Runtime exception.
This is happening only in Intellij background tasks.
#org.jetbrains.idea.maven - Cannot reconnect.
java.lang.RuntimeException: Cannot reconnect.

How can I fix this problem?
回答1:
Just guess.Have you configured a proxy on localhost?It seems that IDEA tried to connect to your localhost.
回答2:
It was the issue with Intellij Remote server manager. Editing /etc/hosts and making sure only one entry exist which points to localhost.
127.0.0.1 localhost
Hope the answer helps if anyone facing the same issue.
